Aim:Peak atrial longitudinal strain (PALS) is used to evaluate left atrium (LA) function in patients with mitral stenosis (MS), before and after percutaneous transmitral commissurotomy (PTMC) and mitral valve replacement (MVR).Methods:Patients with severe symptomatic MS, who were referred to our echocardiographic laboratory for a diagnostic examination before cardiac surgery or PTMC from October of 2014 to October of 2015, were included in the study.Result:The peak systolic global LA strain improved post-PTMC (P < 0.001) and post-MVR (P = 0.012). This difference was statistically highly significant.Conclusion:PALS is impaired in patients with severe symptomatic MS and improved acutely after treatment and may be a good indicator of LA function and may predict the right time for intervention on mitral valve.
A 40-year-old male patient presented with dyspnea on exertion and palpitation from 2 months ago. Physical examination revealed normal vital sign and a systolic murmur grade 3/6 in aortic area. Echocardiography revealed unicuspid aortic valve with an eccentric orifice, calcification, and aortic valve area of 0.9 cm2. This case report highlights the usefulness of three-dimensional echocardiography for the determination of number of aortic valve cusps, presence of raphe and morphology of valve.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
